Description

SSN1SLQ4A overview

Huawei OSN7500 SSN1SLQ4A 4xSTM-4 optical interface board. The SLQ4A can be used on the OptiX OSN equipment series to transmit and receive STM-4 optical signals. The SLQ4A converts the received optical signals into electrical signals and sends the electrical signals to the cross-connect side. In addition, the SLQ4A converts the electrical signals sent from the cross-connect side into optical signals and transmits the optical signals.

Valid Slots

The SLQ4A can be installed in slots 1–8, 11–18, and 26–31 in the subrack.

Basic functions Transmits and receives 4xSTM-4 optical signals.
Specifications of the optical interface
  • Supports different types of standard optical interfaces, namely, the I-4, S-4.1, L-4.1, L-4.2, and Ve-4.2.
  • The characteristics of the optical interfaces of the I-4, S-4.1, L-4.1, and L-4.2 types comply with ITU-T G.957.
  • The characteristics of the optical interface of the Ve-4.2 type comply with the standards defined by Huawei.
Specifications of the optical module
  • Supports the detection and query of the information about the optical module.
  • Provides the ALS function. The optical interface supports the setting of the on/off state of a laser.
  • Supports the usage and monitoring of the SFP optical module, which facilitates the maintenance and upgrading of the optical module.
Service processing Supports the VC-12 services, VC-3 services, VC-4 services, and VC-4-4c concatenation services.
Overhead processing
  • Processes the section overheads of the STM-4 signals.
  • Supports the transparent transmission and termination of the path overheads.
  • Supports the setting and query of the J0, J1, and C2 bytes.
  • Supports one to four channels of ECC communication.
Alarms and performance events Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Protection schemes
  • Supports the Two-fiber ring MSP, Four-fiber ring MSP, Linear MSP, SNCP, SNCTP, and SNCMP.
  • Supports the fiber-shared MSP and SNCP and processes eight sets of K bytes. A single optical interface supports two MSP protection rings, and one SLQ4A supports a maximum of eight MSP protection rings.
Maintenance features
  • Supports inloops and outloops at optical interfaces.
  • Supports inloops and outloops on VC-4 paths.
  • Supports warm resets and cold resets. The warm reset does not affect services.
  • Supports the query of the manufacturing information of the board.
  • Supports the in-service loading of the FPGA.
  • Supports the upgrade of the board software without affecting services.
  • Supports the press-to-collect function in fault data collection.
